My invention relates to an improved drive mechanism for linter gins andthe like,'-its ch-iei object being to render easy-and simple the removalof the-drivingbelt or the sawcylinder so thatirequentchanges of thelatter can-be accomplished with theg'reatest ease and facility.

In considering the application of my invention to linter"gins; it isnecessarytounderstand that belt long enough to be crossed, thoughTsometimes it is driven by what isterrned a serpentine belt drive. The floatshaftusu'a'lly has pul- 1eys -at both' ends driven- 'by open belts fromseparate line shaft pulleys. The brush shaft is driven by an open beltfrom itsline'shaft-pul-ley. customarily: the saw cylinder drivelbelt isarranged atoneend of the linter and the brush drive belt at the otherend. There is normally no occasion to I dis'turb thedrive to the brushor-ifloat, butsince 'the"saw' 'cylinder has to ;be removed and changedevery few hours, it is-a 'but if 'the line shaft on which the saw"cylinders pulley is located is set low enough, i. e.',

close enough-to thesaw cylinder, to permit of the belt 'b'eing' readilyreached and thrown :osor o'n'to its drive=pul1ey, then it will be foundfor a cross d'rive belt-to work satisfactorily." 0n

Y

The object'of'mynpresent invention 1 is to deelements are so arrangedand related to each other that an operator can, with th'ergreatestease,change the saw cylinders-and I accomplish this withoutthe employment ofa di-r'ect driving belt from the overhead line shaft to. the saw'cylinder.

More particularly, my invention contemplates taking the drive for thesaw cylinder offlof' the brush shaft, preferably arranging the drivetothe. saw cylinder at the opposite .end or ,the brush shaft from thatreceiving the drive from theoverhead shaft. r Further,my'inventioncontemplates the employment of a floating pulley driven fromthe 7 brush shaft and connected by a short open driving belt with thesaw cylinder'pulley, the floating pulley being adapted to permit thisbelt to be eased in the simplest possible manner when it is desired toremove and replace the belt. 1 I'My invention; further contemplatesdesigning the floating drive for the saw-cylinder drive belt .50 that'itwill automatically and inproportion to the load thereon. tightenreversely that dIiV-r brush shaft and thereby to tighten the belt, at xv the same time leaving the bearing free to be readily swung by .handtoward the saw cylinder to ease the. belt and permit it to be thrown offof the saw" cylinder pulley. i'

- .My inventionfurther comprises the novelide tails of construction andarrangements of parts, which will be better understood by reference. to

Fig.- 1 is an end elevation of a linter gin I equipped with .my'improved driving mechanism.

Fig. 2 is an enlarged detail viewt'aken on the line lI-II of Fig. I1 andshowing both ends of I the brush shaft with the brush-cylinder brokenaway. 1 I I Similar referenceunumerals refer to similar partsthrough'outthe'drawings. I In the embodiment vof my invention illusprising endframes 5" with a hinged breast 6 fast, in the bearing housing 38. Theroller bear- 'pulley 13.. changed the pulley 33 can in like manner beand a feed hopper '7 carrying brackets 8 which support suitable bearings9 for an overhead drive shaft 10.

The internal mechanism of this linter gin, being of standardconstruction, need not be shown or described further than to state thatits feeder mechanism in the feed hopper is adapted to be driven by thefeeder drum 11; its cylinder 12 has a driving pulley 13; its brushcylinder 14 is driven by the pulley 15; and its'float is driven bypulleys 16 at each end thereof. These float pulleys are driven by openbelts 17 from flanged pulleys 18 fast on the driveshaft 10. A pulley 19on the brush sh ft by means of the open belt 20 drives the feeder pulley11. A pulley 21 on the drive shaft '10, by means of an open belt 22,drives the brush pulley 15.

Th linter parts, and thedrivestherefor as thus far described, are allstandard and may be varied without departure from my invention vhich isconcerned more particularly with a new and improved drive for the sawcylinder pulley 13 which will now be described.

Referring more particularly to Fig. 2 it will be seen that the brushshaft has one end 23 which projects beyond the rollbearing 24 thereforin the frame 5 an is received in a floating gear oase25 which'houses apinion 26 fast on the brush shaft. This pinion a pinion 2'? fast on asleeve 31 mountedby means of roller bearings 28 upon a stud shaft 29'that is mounted fixedly in aboss 30 in the underhungportion of thefloating gear case 25. The gear 27 is housedwithin'the gear case 25 butvthe sleeve 31 extends through a suitable opening in the side plate 32that closes the gear case and on the exposed outer end of the sleeve 1mount fast a flanged pulley. 33.

A suitable cap 34 closes the outer end of the sleeve .31 and has an oilplug 35 therein. An oil drain 36 is provided in the bottom of the gearcase 25 which at its top has a cylindrical sleeve or rocker bearingelement 37 that is mounted to rotate in the bearing housing 38 fortheroller bearing 24. Thissleeve 3'? has a circumferential channel 39which receives a pin 40 in the bearing 38, the, pin serving to permitvthe gear case to rock freely in its bearing 38 about the brush shaft asan axis while holding it against axial displacement. The sleeve 37carries suitablebearing elements 41 and 42 which coact respectively withthe brush shaft extension 23. and with the sleeve 44 that is screwed onthe shaft 23 and carries the inner race of the bear.- ing 24. The outerrace of said bearingis made ing elements are held in place by a retainerring i5 screwed on the threaded end of the sleeve 44.

A short open belt 46 passes from, the grooved floating pulley 33 to thesaw cylinder pulley '13 and this constitutes my improved floating driveto the saw cylinder.

From the foregoing it will be seen that from the line shaft pulley 21the reverse drive to the saw cylinder is transmitted through belt 22 andpulley 15 to the brush shaft and thence through gearing 26 and 2? andsleeve 31 to the floating drive pulley 33 and thence by the short openbelt 46 to the saw cylinder. 'To change the saw cylinder it is onlynecessary to swing the gear case 25 clockwise aboutshaft 23 toward thesaw cylinder, thereby easing belt 46 and permitting it to be readilythrown off the saw cylinder After the saw. cylinder has been ready forservice.

may be of any type and its pended claims.

swung toward pulley 13, permitting the ready replacement of the belt 46and then the drive The pulley and its swinging drive is so hung that itat all times keeps tension on the belt 46 which increases underdrivingconditions, Y 7

It will be noted by reference to the arrows in 1 that the thrust fromthe driving pinion 28 imparted to the pinion 27 mounted in thedirectionabout the brush such tension will be in proportion to the power re rredto drive the saw cylinder. I thus ob.- tain an easy removal andautomatic tension adjustment of a short open driving belt for a sawcylinder by having the hanger supporting the driving element of the beltmounted free to rocl; towards and from the saw cylinder pulley,v

Obviously the floating drive can be placed at either end of the brushshaft, the end remote from the pulley 15 being selected as being mostconvenient of application. Thedriving belt 46 pulleys '13 and 33 arepreferably flanged, r H
